Troubleshooting Guide
SYMPTOM LIKELY CAUSE ACTION
Bad load detect. Detects open
or short condition on the
antenna output or cable.
1) Check that the RF cable is
connected and in good condition.
Perform continuity check of center
conductor and shield. Check for a
shorted cable. Check for
intermittent connection in the RF
cable.
2) Check the antenna for opens,
shorts, resistive ground plane
connection.
3) If this error code persists there
may be a problem with the antenna
installation. This can be checked
with a VSWR meter.
3 Flash Error after
performing Self-Test
Antenna mismatch causes
cable length to affect
sensitivity of load detector
circuit. Also refer to PAN012 at
http://www.artex.net/support-
resources/documents.php?fold
erid=8
.
1) Change cable length by about 5”.
Contact Artex Technical Assistance
to request extension cable P/N 611-
0001.
4 Flash Error after
performing Self-Test 406 MHz or 121.5 MHz output
power too low. Also may
indicate 406 MHz frequency
not correct.
1) Check coax cable and connections.
2) Check antenna installation.
3) Check that the frequencies are
within acceptable limits.
4) Change cable length by about 5”.
5 Flash Error after
performing Self-Test Indicates that the ELT has not
been programmed, or has
been programmed improperly.
1) Verify 406 MHz programming.
Reprogram to short message.
6 Flash Error after
performing Self-Test G-switch loop between pins 5
and 12 at the D-sub connector
not installed – ELT will not
activate during a crash.
1) Check that the harness D-sub
jumper is installed by verifying less
than 1 ohm of resistance between
pins 5 and 12.
2) Install jumper wire if missing.
